The behavior of an object in Python is determined by its type (type). The so-called type is support for certain operations. Numeric objects are basic elements in any programming language and support math operations such as add, subtract, multiply, and divide. Python's numeric objects have integers and floating-point numbers, and support various mathematical operations such as +,-,*,/etc. Without these operators, the program can only use function calls

　　expr is for Tcl-to-do math type operations. It takes all of its arguments ("2 + 2" for example) and evaluates the result as a Tcl "expression", and returns the value. Many commands expr use behind the scenes of order if to evaluate test expressions, such as, and loops. for tip: enclosing the arguments to in expr curly braces would result in faster code. So do expr{$i*10} instead of simplyexpr$i*101) Operators- + ~ !　　unary minus, unary Plu
